Description

We are migrating to manage some (eventually all) of our ACI tenants complete configuration via terraform using the CiscoDevNet/aci provider. We use multicast, multicast route-maps, inter-vrf multicast. Currently these objects/classes are not supported by the ACI provider and we have to use the aci_rest_managed resource type.

Classes we would like supported:
pimCtxP
pimStaticRPPol
pimRPGrpRangePol
rtdmcRsFilterToRtMapPol
pimInterVRFPol
pimInterVRFEntryPol
rtdmcRsFilterToRtMapPol
igmpIfP
igmpRsIfPol

APIC version and APIC Platform

Terraform Version: 1.8.3 (Using Terraform Enterprise)
CiscoDevNet/aci provider Version: ciscodevnet/aci v2.15.0
ACI APIC Version: v5.3(2c) (on-prem APIC controllers)

Current 'hard' Terraform Configuration

This is an example of what we have to do now:

  dn         = "uni/tn-TENANTA/BD-BD-192.168.160.0-24/igmpIfP"
  depends_on = [aci_bridge_domain.BD-192_168_160_0-24]
  class_name = "igmpIfP"
  child {
    rn = "rsIfPol"
    class_name = "igmpRsIfPol"

    content = {

    }
  }
}

  depends_on = [aci_rest_managed.CORE-INTERVRF]
  child {

    content = {

    }
  }
}

Thanks for your consideration

@sthiffea-tmx Thank you for opening this issue. We will add it to our to-do-list and look into it.
I believe that we may already have resources for igmpIfP and igmpRsIfPol but I might be mistaken.
